No Thermal Zone with a Sager NP3760 (Clevo M375E/M375W) and kernel 2.6.9 (DSDT available)

(Please CC me, I am not a member of the list)

Thermal zoning is not detected by the stock ACPI code in 2.6.9 on my
Sager NP3760 laptop (a rebranded Clevo M375E or M375W, IIRC). iasl
20040918 spits out these errors when attempting to compile the
decompiled DSDT:

ASL Input:  dsdt.dsl - 4818 lines, 154622 bytes, 2139 keywords

Do any of these errors have anything to do with it?

2.6.7, 2.6.8.1 and 2.6.9 have all failed to detect the thermal zone on
this machine; should I investigate a BIOS update?

The DSDT is available here:

Thanks in advance,
